Application-filed May 7, 1925. Serial No. 28,713.

To all whom it may concern:

Be it known that I, RALPH ROY KnMMIs, a citizen of the United States,residing at El Paso, in the county of El Paso and State of Texas, haveinvented certain new and useful Improvements in a Rotary Hairbrush, ofwhich the following is a specification.

The present invention appertains to improvements in electricallyoperated rotary brushes, and is more particularly adapted for use as arotary hair brush which will provide an eflicient means for massagingthe Another important object of the invention is to provide a rotarybrush which by its use will produce increased circulation of the bloodinthe scalp and thereby benefit the roots of the hair and the scalp.

Another important object of the invention is to provide a rotary brushof this nature which is easily assembled, or disassembled so that thesame may be cleansed and sterilized, and thus be useful around barbershops, beauty shops, etc.

Another important object of the invention is to provide a demountablebrush which may be reversed in a frame, thus preventing 'the bristlesfrom becoming permanently curved in one direction, as is the case wherea brush rotates continually in one direction. Another very; importantobject of the invention is to provide a frame with a demountable brushtherein whereby it'is possible to change the br'ush, depending upon thesize desired, or the degree of stiffness required in the bristles. Astill further important object of the in vention is to provide a rotarybrush which is exceedingly simple in its construction, in-' expensive tomanufacture, strong, durable,

reliable in operation, easy to manipulate,

, not liable to easily become out of order, and

otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in view, as will appear as thedescription proceeds, the invention resides in certain novel features ofconstruction, and in the combination and arrangement of parts as will behereinafter more fully described and claimed.

In the drawing g Figure 1 is any elevation of the rotary brush,

Figure 2 is a fragmentary elevationshowing one side of the frame in adisengaged position, I

Figure 3 is a section taken longitudinally through the brush and theframe, V

Figure 5 is a fragmentary end view of one side of the'frame,

V Figure 4 is a sectional view through the brush proper, and

Figure 6 is an elevation of one side of the frame.

Referring to the drawing in detail, it will beseen that A designatesgenerally the fork shaped frame which includes the handle 5, and thesides 6 and 7 mounted on the base 8. The side 6 has formed at itsterminal an outwardly extending cylindrical casing 9 havinga shaftbearing 10 threaded in the outer end thereof for the reception of aflexible shaft 11 of conventional construction. A tubular pintle 12extends inwardly from the casing 9 havingthe head portion 13 thereoffixed in the casing by a set screw 14, or in any other suitable manner.shaft is adapted to continue through this tubular pintle.

The,

The side 7 is pivoted at its lower end to v the base 8, as at 15, and isprovided with I a groove 16 for receiving an extension 17 of the base 8when said side is disposed in parallelism with the fixed side 6. A U-shaped member 18' is pivotally engaged as at 19 with the side 7, andfits overthe extension 17 and the side'7 thereby holding said side 7rigidly in parallelism with the side 6. A cylindrical casing 20 isformed on the outer end of the side 7, and extends outwardly. When theside 7 is disposed in parallelism with the side 6 said-casing 20 iscoaxially aligned with the casing 9. A

, pintle 21'extends inwardly from the casing 20 having its head22'slidable therein. A

pin 23 extends from the head through an L-shaped slot 24 provided in thecasing 20 so that the pintle 21 may be moved inwardly and engaged'withthe offset portion 25. A cap 26 is threaded to the end of the casing 20and slidably receives a stem 27, which is threadedly engaged with thehead 22 of the pintle 21. A spring 28 is disposed in the casing betweenthe cap 26 and the head 22 and normally holds the pintle 21 in itsextended position.

The rotary brush indicated generally by the letter B includes a drum 30having disposed therein a. shaft engaging member 35 havinglongitudinally extending ribs 35"011 its exterior and located axiallywithin the drum, bristles 31 are disposed in groups,

and the groups pierce the drum .30 so as to extend radially therefrom;Said bristles are suitably held in a base or core 30 within the drum 30and the hubs 32 are secured in any known manner in the ends of, saiddrum. Bushings 33 are fixed in place in the hubs by set screws 8%. Jfheibushings 33 are rotatable on the pintles 12 and 2:1. The end of theshaft 11 may be projected through the :members 10 and 12-:and engaged inthe member 35.

From the above description it will be seen that by pulling out upon thehandle provided on the stem 27, the 'pintle 21 maybe disengaged from theadjacent hub 32 ofrthe brush B, :and then by turning the pintle 21 so asto engage the pin 23 in the offset portion'25' of the slot :24, :saidspring :28 may be held under-compression:and the pintle 21 is held outof engagement with the brush or in a retracted position. a a

By releasing the pivoted :U-shaped member 18. the-side Tmay be swung tothe position shown in Figure 2, so that the brush may be removed andreversed, if desired, or another brush may be put in place thereof. Itwill therefore 'be :seenxthat 'the brush is very easily assembled "anddisassembled with respect .to "the frame, and therefore may be readilycleansed and sterilized as desired.

The present embodimentof the invention has-been disclosed in detaihandhas been given merely by way of example. Thisembodiment of the inventiongives excellent results, and attains all the features of ad vantageenumerated as desirable in the statement of the invention and the abovedescription. It is apparent, however, that numerous changes in thede-tailsof construction, in thesizes, in the proportions, and

the combination and arrangement of parts may be resorted towithoutdeparting fronr thespirit or scope :of the invention ashereinafter claimed or sacrificing anyof its ad vantages.

Having thus described the invention,

what I claim as new and desire to secure by Lettters Patent isz- F v 1.,In a device of the class described, a frame, comprising a fixed side anda hinged side, means for holding the hinged side in parallelism with thefixed side, casings extending outwardly from the sides coaxially alignedwhen said sides are in parallelism, pintles in the casings, thepintle inthe casing, on the hinged side being slidable, means for holding thepintle which is slidable, normally extended, means for retracting the:sameand a brush adapted to be rotatably supported by said pintles.

2. In a device of the class described, a frame, comprising a ifixed sideand a hinged side, means for holding the hinged side in parallelism withthe fixed side, casings :extending outwardly from the sides coaxiallyaligned when said sides are in parallelism, pintles in thecasings, the:pintle in the easing on the hinged side :being. slidable,ymeans forholding the pintle which is slidable normally extended and means forretracting the same, said casing on the hinged side 'being prov ded withan L-shaped slot, a pinextending from the pintle in the. last mentionedcasing through the slot, anda brush adapted to be rotatably supported by:said pintles. I Y

3. A frame for receiving a rotary brush adapted to be operated by aflexible shaft and includingza-handle,:a'fixed side, a hingedside, meansfor holding the hinged side in parallelism with the fixed side,cylindrical casings mounted on the ends of the sides,

and coaxially aligned when the sides are disposed in parallism, a hollowpintle provided in the casing on the fixed side, a slidahle pintle inthe iother casing, an :L- shapedslot in the last mentioned casing, a pinin the slid-able 'pintle extending through the slot, a-spr-ing in thelast men-1 tioned casing holding the ipintle which is slidable,normally'extended, means for retracting the slidable pintle, and a brushadapted to berotatably supported by said pintles. v v
